OIL-FLOWING DEVICE.

Specification of Letters Patent.

Eatented Aug. 29, 1905.

Application filed January 3,1905. Serial No. 239,357.

To all whom it may concern Be it known that I, J OHN KAMBIsH, J r., acitizen of the United States, and a resident of Piney, in the county ofVVetzel and State of West Virginia, have invented a new and ImprovedOil-Flowing Device, of which the following is a full, clear, and exactdescription.

The invention relates to apparatus for raising oil, water, or otherliquids in wells by the use of a gaseous fluid under pressure.

The object of the invention is to provide a new and improved oil-flowingdevice arranged to utilize the gas frequently found above the oil stratafor flowing the oil to the surface and for collecting and-saving thesaid gas.

The invention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter and then Each ofthe well-casings A is closed at the.

upper end by a head or cap B, and in the easing A extends a flow-pipe C,terminating at its lower end in the perforated inlet-pipe D, located inthe oil-bearing strata, so that the oil passes through the perforationsinto the inlet-pipe D and into the lowermost section U of the flow-pipe,which lowermost section connects at its upper, somewhat-reduced, ornozzle end with an ejector E, connected with a supply to gas underpressure to cause the ejector to force the oil up through the flowplpe.

The ejector E is provided with a checkvalve F in its gas-supply pipe G,opening into a gas-reservoir H, surrounding the flowpipe at its lowerend and preferably attached to the perforated inlet-pipe D, as plainlyshown in Fig. 2. The upper end of the reservoir H is connected with areturn gas-pipe I, extending upward through the head B and having areturn branch I, connected with the head B, the said branch having avalve I under the control of the operator for regulating the flow of gasthrough the return gaspipe.

By the arrangement described it will be seen that the gas in the lowerend of the oilwell collects, accumulates, and rises in the casing A andis conducted by the return gaspipe I, reservoir H, and pipe G to theejector to supply the latter with gas under pres ure for the properworking of the ejector. The oil and gas [lowing up the flow-pipe C isdischarged intothe top of a separating-tank J, in which the gas and oilseparate, the said tank being connected at its bottom by a pipe K withan oil-tank L, into which the oil is forced from the tank J by thegas-pressure in the tank J. Gas rising in the tank L can be conducted bya pipe N, having a'. valve N, to the tank J. The gas in the tank J isconducted by a gas-line 0, having a valve 0, to burners for burning thegas.

Having thus described my invention, I claim as new and desire to secureby Letters Patent -1. An oil-flowing device comprising a gascollectingcasing for collecting the natural gas in the well, a flow-pipe-for theoil and gas, an ejector in the said flow-pipe, a reservoir in the well,a return gas-pipe connecting the said casing with the said reservoir,and a connection between the reservoir and the ejector.

2. An oil-flowing device comprising a gascollecting casing forcollecting the natural gas in the well, a flow-pipe for the oil and gas,an ejector in the said flow-pipe, a return gaspipe connecting the saidcasing with the said ejector, a separating-tank for receiving the oiland gas, an-oil-tank for receiving the oil from the saidseparating-tank, and a valvecontrolled pipe for conducting gas rising inthe oil-tank to the separating-tank.

3. An oil-flowing device comprising a wellcasing closed at the top, aflow-pipe in the said casing and extending through the said top, anejector in the said flow-pipe, a return gas-pipe leading from the saidtop down into the well -casing, a reservoir connected with the returngas-pipe, a connection between the reservoir and the said ejector, tosupply the latter with gas-pressure, and a check-valve in the saidejector.

4:. An oil-flowing device comprising awellcasing closed at the top, afiow-pipe in the said casing and extending through the said top, anejector in the said flow-pipe, a return gas-pipe leading from the saidtop down into the well-easing, a reservoir at the lower end of the saidreturn gas-pipe, and a supply-p1pe leading from the said reservoir to'the said casing closed at the top, a flow-pipe infithei said casing andextending through the said top, an ejector in the said flow-pipe, areturn gas-pipe leading from the said top down into the well-casing, areservoir at the lower end of'the said return gas-pipe, a supply-pipeleading from the said reservoir to the said ejector, to supply thelatter with gas under pressure, and a check-valve in the saidsupplypipe.

6. An oil-flowing device comprising a wellcasing closed at the top, aflow-pipe in the said casing and extending through the said top, aperforated inlet-pipe communicating with the lower end of saidflow-pipe, a return gas-pipe leading from the said top and provided witha valve, the said return-pipe extending through the said top down intothe well-casing around the said flow-pipe, a res- .ervoir at the lowerend of the return-pipe,

the said reservoir being attached at its lower end to the perforatedinlet-pipe, and an ejector connected with the said flow-pipe and thesaid reservoir.

7. An oil-flowing device comprising a gascollecting casing forcollecting the natural gas in the well, a flow-pipe for the oil and gas,a perforated inlet-pipe communicating with the lower end of saidflow-pipe, an ejector in the said flow-pipe, a return gas-pipe leadingdown into the well-casing, a gas-reservoir connected at its upper endwith the return gas-pipe, a supply-pipe leading from the gas-reservoirto the ejector, a separating-tank for receiving the oil and gas from theflow-pipe, and an oiltank for receiving the oil from the saidseparating-tank.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
